The appropriate pre-separator for multiple tasks
Lybover pre-separators are used for discharging coarse, fine and combustible particles, protecting the filter media while minimizing wear and tear. Additionally, they collect a larger dust volume while acting as spark pre-separators to help minimize the risk of fire.
Depending on the required level of pre-separation and the material to be separated, three different types are available.
1) Material- pre-separator (MVA, MVAS)
Material pre-separators MVA are available in different materials and consist of a cylindrical upper section with openings for dirty and clean air and a funnel-shaped lower section with a spiral deflector.
MVAS = reinforced construction
Mechanical separators operate according to the principle of centrifugal force. Dirty air enters the cylindrical chamber of the spark pre-separator through an external inlet.
The dust particles are propelled against the outer wall and spiraled downward to the funnel-shaped discharge. Clean air exits the spark pre-separator through the top.
Advantages:
- Protection of the filter elements
- The risk of fire is reduced
- Compact and low design
2) Impact separator (PA):
Compact impact separator for discharging e.g,. sparks, available in a variety of materials, and for direct attachment to filter systems.
The dirty air enters the pre-separator at the top and is deflected into the hopper area. If sparks are introduced, the thermal energy of the particles is diminished and large particles are separated. Disposal is in a bucket mounted underneath. The cleaned air is discharged out the rear exhaust.
Advantages:
- Protection of the filter elements
- The risk of fire inside the filter is reduced (by discharging highly energized sparks)
3) Cyclone separator (AS, ASS):
High performance cyclone separators are available in different materials and consist of a cylindrical upper section with openings for dirty and clean air and a conical lower section with discharge outlet.
ASS = reinforced version
Mechanical separators operate according to the principle of centrifugal force. Dirty air enters the cylindrical part of the cyclone through the adjoining intake. The dust particles are propelled against the outer wall and spiralled downwards through the funnel-shaped discharge. The cleaned air exits the cyclone through an upper exhaust air outlet.
Advantages:
- Protection of the filter elements
- High fractional separation efficiency
- More suitable for higher air flows up to 125 000 m 3/h.
